Luf Linkert (Old Slot Racer) very kindly mailed me the CAD file of his 8x4 rally track.It needed conversion to DXF.- which was done with a free download.
A local small factory with a CNC router cut it out after I gave them the file on a memory stick.They charged £80 including supplying the MDF. (A sheet of 18mm MDF is £16-20 from one of the DIY supermarkets.)
This produced a perfect replica of Luf's track,easily taking the small gradients necessary to finish it.
The real crunch, especially for old farts that aren't very good with computers, is getting the initial CAD file done. I bought a "teach yourself CAD"course on a disc; it makes a good if rather expensive coaster to stop my tea mug making rings on the kitchen table!I might have been better finding a cooperative teenager to do it for me - if there is such a thing as a cooperative teenager.( I'm sure there is; they're just somebody else's).
For those who are good at writing CAD files, I'm sure that like music to musicians, it isn't that difficult; and I'm surprised that no-one has made a cottage industry out of selling a range of slot tracks on ready-to-use CAD files, that people all over the World could buy and take to their friendly local CNC router shop.
